CHARLES H. HUNT, OF LAWRENCE, MASSACHUSETTS.

THROS'ILE SPINNING-MACHINE.

Specification forming part of Letters Patent No. 9,283,.dated September 28, 1852; Reissued May 17", 1864, No. 1,672.

To all whom t may concern Be it known that I, CHARLES H. HUNT, of Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful improvement in that part of the mechanism of a throstle spinning-machine by which the vertical movements of the spindle are regulated or produced in order to lay the yarn in the proper manner on the bobbin; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying. drawings, letters, gures, and references thereof.

Cf the said drawings Figure 1 denotes a top view, Fig. 2 a front side elevation, and Fig. 3 an end elevation of a throstle frame containing my improvement.

In the said drawings only one spindle and its flier are represented as applied to each of the sides of the frame, it being understood that the spindle and flier rails of each side are to be supplied with any number of such as may be required.

A (Figs. 1, 2, and 3) is the stationary iier rail, B the movable spindle rail, C the Hier, D the. spindle, E, E, the stationary guide rods of the spindle rail. The said spindle rail is supported by two chains F, F, that are attached to it and respectively pass over two pulleys Gr, Gr, that are placed in arms H, H, that extend upward from the horizontal rail a of the frame I. These chains are respectively attached to the ends of long rods or bars c, c, that have chains CZ, d, connected to their opposite ends, the

Vsaid chains d, d, being wound around and attached to a horizontal shaft K, as seen in Fig. 4:, which denotes a cross section of the shaft and shows the chain and the arc or semicircular link e thereof, that is employed to extend partly around the shaft when the chain is quite wound up. Each spindle rail has two of these chains extending from the shaft K.

In the process of laying the yarn on the bobbin the shaft K is not only to have a regula, reciprocating, rotary, movement imparted to it such as will lower and raise the spindle rail, but between each two of such movements it is to be turned a little so as to unwind the chains from it in order to let the spindle rail drop a short distance, in order that the building up of the yarn on the bobbin may gradually take place.

The mechanism that constitutes my improvement is to effect such movements, and is as follows:

A gear wheel L is fixed on the shaft K and made to engage with a pinion M that is firmly fastened on the inner end of a horizontal shaft N, see Fig. 1 and Fig. 5, which is a vertical section taken through and in line of the axis of the shaft N. On the shaft N are two wheels O, P, which run or turn freely on it. The inner of. these wheels, viz, the wheel O, has a small ratchet wheel R aflixed to its inner side, which ratchet wheel works in connection with a spring click S that is fastened to the periphery of a wheel T, that is fastened to and on the shaft N, the whole being shown in Fig. 6, which is an inner side view of the wheel O. The said wheel O is made with ratchet teeth f around its periphery and with a row g of pins extended from its inner side, as seen in the drawings, there being the same number of pins or their equivalents as ratchet teeth f.

An escapement lever formed of an arm lo and two pallets z', 70, arranged with respect to one another, as seen in the drawings, is made to rock on a fulcrum Z that projects from the wheel P and over the periphery of the wheel O. One of the pallets (viz. i) of this escapement lever operates in connection with the ratchet teeth of the wheel O, while the other pallet (viz. 7s) operates in connection with the row of pins that extend from the side of such wheel O.

The outer face of the wheel P has two concentric circular grooves or paths m, a, made in it, each of which is made by means of a semicircula-r groove to run into the other at their ends, as seen in Fig. 7, which is a side view of the wheel. Between these grooves there is a concentric row of pins 0, o, arranged at equal distances apart, and so as to engage with a toothed pinion 79, that is fixed on a shaft g, that is supported on the lower end of a pendulous or vibrating arm 1", that is hung on a shaft s, suitably supported at the upper part of the frame of the machine. There is a pulley fixed on the shaft g, and another one (u) fixed on the shaft s, an endless belt o being made to pass around the said pulleys. By putting the pulley u and its shaft s in revolution by any suitable means while the throstle frame is in action, the pinion p will be put in rotation, and as the inner end of its shaft is inserted in the path formed by the concentric grooves m, n, and their joining semicircular grooves, the pinion will so act on the rows of pins 0, 0, as to produce a reciprocating rotary movement of the wheel P. When the Wheel P is moved in a direct-ion such as will press the pallet z' of the escapement lever against the next adjacent ratchet tooth of the wheel O, such wheel O will be put in rotation and will continue so until the arm h of the escapement comes into contact with a stationary stud or pin y arranged as seen in the drawings. The pressure of the arm against the stud causes the pallet z' to rise to the top and above the tooth or escape over it in a manner similar to that in which the pallet of an escapement of a pendulum escapes over a tooth of its toothed Wheel. The two pallets i, k, act on the rows-of ratchet teeth and pins on thev wheel O, very, if not essentially, like the pallets of a common pendulum escapement, so that at the next time the escapement is moved in a direction toward the stud y, it will pass and act against that tooth next to the one it last slipped over. The said slipping by a tooth of the wheel O, allows the shaft K to turn a little, so as to allow the spindle rail or rails to drop a shortdistance in order to increase the up.-

ward wind of the yarn on the bobbin or lower the bobbin a little in order that the yarn may be wound higher up on it. By putting a crank on the outer end of the shaft N and turning it in the right direction or that denoted 'by the arrow we cause t-he chains of the shaft K to be wound up thereon so as to elevate the spindle rails to their highest positions, preparatory to the operation of spinning on another set of bobbins.

What I claim as my invention is- The escapement wheel O, its escapement lever (composed of the arm h and pallets z', 7c) and stud y, in combination with the reciprocating rotary mechanism, composed of the wheel P, its concentric and endless grooves, row of pins, the pinion p, and pendulous bar or arm 1', the whole being applied to give motion to the shaft N, its

pinion, the gear of the shaft K, and the said shaft K, in order to effect the movements of the spindle rail o-r rails, essentially as above specified. y

In testimony whereof I have hereto set my signature, this eleventh day of May,

CHARLES H. HUNT. Witnesses:
